I think there is no hard coded limit. More hosts means more memory consumed by Ansible. Each host has a set of variables and facts for which memory space is allocated. Number of parallel Ansible processes, and thus CPU cores used, can be controlled by `-f` parameter.

That being said, control node resources are the only limit.

For extra large number of hosts, AWX supports distributed scalable Ansible invocation.
